Hello Heinz.
I have never used a K&N filter so I can't really tell you any thing about them. The Pipercross is as far as I am aware of similar construction to the K&N so I should think there is not much to choose between them. The prices are pretty similar as is the fitting in the filter box.
A cleaning and retreating kit is available for the Pipercross . I think I paid abou twelve quid for one but as yet I haven't used the kit.
I am sure some one will put you(and me ) wise about K&N filters ,they seem to be a lot more popular than the Pipercross.
I have an excellent record of buying the wrong one with things like this.
Sorry I can't be any more helpful to you.
Best wishes .
Trodnik
